Dehydroepiandrosterone Sulfate (DHEA-S)
DHEA-S is the sulfated storage form of the most abundant circulating adrenal steroid precursor, serving as a primary biomarker of adrenal reserve and adrenopause.
Standard vs. Optimal Reference Rangesμg/dL
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
80 - 560 μg/dL (Age- and sex-dependent)
General reference distribution across unselected commercial populations.
350 - 500 μg/dL (Male), 200 - 350 μg/dL (Female)
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Synthesized in the adrenal cortex zona reticularis from cholesterol via CYP17A1 (17alpha-hydroxylase/17,20-lyase) and sulfated by SULT2A1. DHEA-S acts as an intracrine precursor converted to androgens and estrogens within peripheral target tissues.
Differential Diagnosis
Elevated Levels (DHEA-S High)
- •Polycystic Ovary Syndrome (PCOS)
- •Congenital adrenal hyperplasia (21-hydroxylase deficiency)
- •Adrenal cortical carcinoma / Adenoma
- •Exogenous DHEA supplementation
Low Levels (DHEA-S Low)
- •Adrenopause (normal biological aging)
- •Adrenal insufficiency (Addison disease)
- •Hypopituitarism
- •Chronic physiological exhaustion or corticosteroid suppression

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Blood draw must occur strictly between 7:00 AM and 9:00 AM to account for steep circadian cortisol and testosterone peaks. Ensure 8 hours of restful sleep prior; night shift work or sleep deprivation severely blunts endocrine pulsatility. Discontinue biotin supplements for 72 hours before thyroid or steroid testing to prevent false immunoassay results. For reproductive hormones in premenopausal females, precisely document the day of the menstrual cycle (Day 3 for baseline follicular, Day 21 for luteal).
Reflexive Testing Protocol:
- Free Hormone Equilibrium Dialysis or LC-MS/MS assay for direct bioavailable hormone quantification
- Pituitary trophic hormone panel (TSH, LH, FSH, ACTH, Prolactin) to differentiate primary vs central secondary endocrinopathies
- Autoantibody quantification (Thyroid Peroxidase Antibodies, Thyroglobulin Antibodies, 21-Hydroxylase Antibodies)
- Pelvic, testicular, or thyroid high-resolution ultrasound imaging to assess glandular parenchymal architecture
- Dynamic endocrine stimulation testing (Cosyntropin/ACTH stimulation test, Dexamethasone suppression test, GnRH test)
